BY GEORGE READ MAHONEY, HORNBAKER AND SCH/CK ATTORNEYS ADJUSTABLE BRACKET ASSEMBLY FOR USE AS A REAR DRAWER SLIDE BRACKET AND THE LIKE BACKGROUND OF THE DISCLOSURE This invention relates to an adjustable bracket assembly which may be used as a rear drawer slide bracket in finally mounted form, which assembly may include two distinct members or parts relatively slidably adjustable in a unique manner, in one form, constantly floating after final mounting, and in another form adjustable only during final mounting, of the assembly on a mounting surface in order to bring a bracket of the assembly into proper alignment for properly maintaining various forms of drawer slides and the like in functional working operation. Certain of the features of the invention are that, in the floating form, the parts of the assembly are positively retained in a constantly floating and adjusting position, while in another form, where conditions dictate, for maximum retention of final adjusted relative positioning between the parts of the assembly, such parts may be particularly formed with unique interfitting and abutting interengagement during the final assembly operation for the mounting thereof on the mounting surface so as to assure that the desired final aligned positioning between the parts of the assembly will be maintained during a long period of functional use. Furthermore, as an additional part of the present invention and where desired with either floating or finally secured forms, the entire assembly may be formed unitary, originally in a flatwise form with a flexible strap extending generally flatwise between these two distinct parts, and during assembly, the one part may be folded over the other as permitted by folding of the connecting strap to particularly assemble the two parts in the finally floating or secure adjusted form.

Most prior constructions of brackets for supporting the rear end of slides used in guiding and controlling drawers and the like have been formed of one piece, usually metal and of welded or stamped form. During mounting for use, the prior brackets are positioned on a vertical mounting surface and retained in place through the use of conventional fasteners, such as wood or metal screws. In such mounting, the fasteners are received through certain slotted openings of the bracket so that in final securement, the brackets may be adjusted relative to the mounting surface properly aligned for receiving the rear end of the drawer slide supported thereon and then finally secured stationary.

Thus, with all of the prior rear drawer slide bracket assemblies to our knowledge, it has always been attempted to securely retain the bracket in a preset, permanently adjusted position exactly aligned for receiving the rearend of the drawer slide supported thereon. Although there are certain drawer slide and related guided drawer arrangements in which permanently adjusted and maintained drawer slides are a vital requirement for proper functioning of the drawers during inward and outward movement thereof, it has been found, according to certain of the principles of the present invention, that many drawer slide and guided drawer arrangements will operate in a superior manner if the rearends of the drawer slides are mounted on a limited adjustably floating rear drawer slide bracket. In other words, with the rear end of the drawer slide mounted by a freely floating rear drawer slide bracket, it has been found that during inward and outward movement of the drawers supported by such drawer slides, the drawer slide will always seek proper alignment, even different at different inward and outward positions of the drawers, for most easily permitting free drawer inward and outward movement, while still providing sufficient guiding by the drawer slide for properly limiting such drawer movement.

Still in other drawer arrangements, however, it has been found that secure permanent, adjusted mounting of the rear drawer slide brackets is important in order that the associated drawer will function smoothly during its inward and outward movement. In such case, the exact vertical positioning of a particular drawer slide bracket most frequently does not present any substantial difficulties and can usually be readily determined prior to any insertion of fastening screws for the exact final bracket positioning. The main difficulty presented with drawer slide brackets requiring secure adjustment is the proper relative horizontal positioning, that is, shifting the brackets horizontally along the mounting surface into exact proper alignment so that the drawer being installed will not bind in its movement forwardly and rearwardly as so guided by the drawer slide being supported by the rear drawer slide bracket. Thus, the major difficulty with the prior rear drawer slide brackets finally retained in a secure position is in the adjustability thereof during installation horizontally along the mounting surface to which such brackets must be secured.

A still further important requirement of rear drawer slide brackets of this finally secured form is that once this relative horizontal adjustment thereof is obtained for proper support of the drawer slide and the proper functioning of the drawer guided by such slide, such adjusted positioning must be positively maintained. Furthermore, such adjustment must be positively maintained over a long period of relatively harsh and abusive use of the drawer and slides supported thereby. In this respect, the prior rear drawer slide brackets of the forms herein discussed have again been lacking as there have been many occasions where read-adjustments and even replacements of the brackets have been required after various periods of use.

OBJECTS AND SUMMARY OF THE INVENTION It is, therefore, an object of this invention to provide an adjustable bracket assembly usable as a rear drawer slide bracket and the like which assembly is formed of two functionally distinct pans, one adjustable relative to the other, in one form, freely adjustably floating throughout use thereof, and in another form, only adjustable during final bracket assembly and securement to a mounting surface, but in either form, final adjusted alignment within the limits required may be obtained with a minimum of time and effort while still producing exact desired results. The unique assembly is comprised of distinct bracket and mounting members, the bracket member ultimately serving as the supporting part for the drawer slide and the mounting member overlying the bracket member and retaining the same mounted on a vertical mounting surface, in one form, freely adjustably floating, and in the other form, securely retained in exact set alignment for the drawer slide support. In the procedure for finally assembling and mounting the bracket and mounting members of the finally securely retained form, such members may be first attached to the mounting surface in a roughly aligned and loosely mounted condition and then finally exactly aligned in exact proper position followed by full tight securement by ordinary fasteners.

It is a further object of this invention to provide an adjustable bracket assembly usable as a rear drawer slide bracket and the like of the foregoing general character which may be provided, when desired, as a unitary assembly capable of original flatwise positioning as originally manufactured and provided, yet conveniently foldable into a final assembly form ready for mounting attachment to a vertical mounting surface and final adjustment for proper alignment. The overall assembly is still formed by the functionally distinct bracket and mounting members but such members are originally connected by a flatwise extending flexible strap. Thus, during final assembly, one of the members is merely folded over the other of the members into proper final assembly, the flexible strap folding upon itself to permit such final assembly and also permitting the constantly floating or final adjustment for proper alignment through the flexibility thereof.

It is also an object of this invention to provide an adjustable bracket assembly usable as a rear drawer slide bracket and the like capable of incorporating all of the foregoing advantageous constructions and functioning capabilities wherein each of the bracket and mounting members may include uniquely cooperable construction elements assuring the establishment of proper mounted alignment of the final bracket assembly for proper functioning as a floating assembly or a permanently secured assembly, depending on the form of the present invention used, and the maintenance of such properly functional alignment, without further adjustment, over a long period of use. In a preferred form of the present invention, the previously discussed assembly mounting member has an opening formed therethrough and a bracket aligning groove in the rearward surfaces thereof encompassing said opening, the bracket member in the final bracket assembly being received in this mounting member groove with a forwardly projecting bracket thereon extending forwardly through the mounting member opening. Thus, when the mounting member is assembled over the bracket member, the bracket member may be adjusted along the mounting member groove, the bracket of the bracket member moving within the mounting member opening, so as to permit the final constantly floating adjusted alignment between the members, or the final clamped adjusted alignment for the final securement of the members.

It is also preferred for optimum final adjustment retainment in the final clamped adjusted fonn to provide a plurality of serrations on each of the member mating abutting surfaces which interengage after final adjustment and during final securement. These serrations are formed at an angle to the direction of positioning adjustment between the mounting and bracket members so that once final adjustment is obtained and final securement takes place, the desired alignment will always be retained by these interengaged serrations in addition to the normal clamping abutment between the member surfaces and against the surface on which the assembly is mounted.

Other objects and advantages of the invention will be apparent from the following specification and the accompanying drawings which are for the purpose of illustration only.

DESCRIPTION OF THE BEST EMBODIMENTS CONTEMPLATED Referring to the drawings, one preferred embodiment of the adjustable bracket assembly of the present invention and of the constantly floating form is illustrated in FIGS. 1 through 4, and this embodiment of the adjustable bracket assembly, as well as that embodiment to be hereinafter discussed, is specifically usable as a rear drawer slide bracket as will be hereinafter described. The embodiment of the bracket assembly of FIGS. 1 through 4 has the parts thereof preferably moulded from one of the usual plastics, such as polypropylene and includes a mounting member generally indicated at 10 and a bracket member generally indicated at [2. The mounting member 10 is formed with a forward outer surface 14 and a rearward surface 16, the rearward surface having a horizontally or longitudinally extending recess or groove 18 formed therein intermediate, preferably midway, transverse dimensions thereof and opening at the longitudinal extremities of the mounting member.

Transverse extensions 20 are formed on the mounting member 10 extending upwardly and downwardly from'the intermediately formed groove 18. Furthermore, an opening 22 is formed completely through the mounting member 10 preferably transversely co-extensive with the groove 18 in the rearward surface 16 and preferably midway of the longitudinal dimensions of the mounting member and the groove longitudinal extension. The opening 22 is, therefore, both transversely and longitudinally closed and encompassed by or totally within the rearward surface groove 18, said opening preferably being rectangular in shape. Also, this results in the opening 22 being intermediate the longitudinal extension of the rearward surface groove 18 so that the rearward surface 16 preferably borders the opening at opposite longitudinal sides of the opening within the groove.

Important to this constantly floating form of the adjustable bracket assembly is the fact that all of the surfaces of the mounting member 10 at or forming the groove 18 including the rearward surface 16 are relatively smooth surfaces so that there are no appreciable obstructions within the groove which would prevent relatively free slidable, particularly longitudinally slidable, movement within such groove. Completing the construction of the mounting member 10, fastener openings 24, preferably longitudinally elongated, are formed through the mounting member transverse extensions 20 and it will be particularly noted in this embodiment that such fastener openings are solely in the mounting member transverse extensions and do not penetrate nor interfere with the groove 18 in the rearward surface 16 of the mounting member.

The bracket member 12 is preferably substantially rectangular in front or rear view, the rear view thereof being shown in FIG. 4, and is formed with a flat, smooth, rearward surface 26 and a flat, smooth, forward surface 28 with the exception of a forwardly projecting drawer slide engaging bracket 30. The drawer slide engaging bracket 30 is integral on and projects forwardly from the forward surface 28 longitudinally intermediate said forward surface and it will be noted that the longitudinal dimensions of the bracket are spaced considerably less than the longitudinal dimensions of the previously described mounting member opening 22, although the overall longitudinal dimensions of the bracket member 12 are generally the same as the overall longitudinal dimensions of the mounting member 10 and the overall transverse dimensions of the bracket member are preferably only slightly less than the transverse dimensions of the groove 18 in the mounting member rearward surface 16, the importance thereof to be hereinafter discussed. Also, the transverse dimensions of the drawer slide engaging bracket 30 on the bracket member 12 are less than, but preferably only slightly less than, the transverse dimensions of the mounting member opening 22 and, most important to this embodiment of the present invention, the thickness of, that is, the forward and rearward dimensions of, the major part of the bracket member 12 excluding the drawer slide engaging bracket 30 is slightly less than the equivalent depth dimension of the mounting member groove 18, again for purposes to be hereinafter described.

In assembly of the constantly floating form of the adjustable bracket assembly, the bracket member 12 is longitudinally slidably positioned in the rearward surface groove 18 of the mounting member 10 with the drawer slide engaging bracket JOprojecting forwardly throughthemounting member opening 22.
